Should I order material by the ton or by the yard?

Either works. Both are standard units for bulk aggregate, and the calculator on each product page takes your numbers and returns a quantity. Order in whichever unit suits your project, then pick a delivery date at checkout. The truck tips the load on site in one pile.

Which stone is best for drainage in Stevens County?

Washed stone with no fines. Drain Rock, also called 7/8 clean, keeps its voids in footing drains, French drains and infiltration trenches, which matters where a perched water table sits on till. 3/4" Crushed Stone suits trench backfill and under-slab drainage.

What do I need to have ready for a bulk delivery?

A clear drop spot the truck can reach, and a quantity settled before checkout. Order by the ton or the yard and size the load with the calculator on each product page. The driver tips the load in one pile on arrival. Pick your delivery date at checkout.

Stevens County 5/8 Minus and Gravel Delivery, WA

Order gravel, stone and aggregate delivery in Stevens County, WA online, by the ton or by the yard, and a dump truck brings it to your site. Washington Rock Supply serves Colville, Chewelah, Kettle Falls, Loon Lake and the towns between.

Start with 5/8 minus, the crushed surfacing top course Washington yards call CSTC. It carries the fines, so it packs hard and sheds water.

Ridges here sit on thin stony soil over granite, gneiss and metamorphic rock, and valley floors hold till, outwash gravel and lake silt.

5/8 minus is the default surfacing course in this state.

Use it for driveways, parking pads, and shed and shop slabs.

5/8 Minus packs down under a truck tire and finishes as a firm, firm-wearing surface. Below it goes 1 1/4 Minus, the CSBC base course with a 1 1/4 inch top size and fewer fines.

It carries load and stays workable on soft spring ground.

Washed stone handles the water. Drain Rock, also sold as 7/8 clean, has no fines, so it keeps its voids in footing drains, French drains and infiltration trenches.

3/4" Crushed Stone does the same job in trench backfill and under-slab drainage.

Flatwork and paths take finer material. Stone Screenings, or crusher dust, beds pavers and flagstone.

Walkway Gravel, the 1/4 minus, packs tight underfoot on garden paths and side yards.

For ground that has to look finished, Washington River Rock armour dry creek beds and downspout splash pads. Top Soil rebuilds lawns, and Shredded Mulch, sold as beauty bark, covers planting beds and tree rings.

Ground Conditions Across Stevens County

This county spans more than one ground region, so conditions change with the site. In the Okanogan Highlands and the northeast corner, ridges are thin stony soil over granite, gneiss and metamorphic rock, with till, outwash gravel and lake silt filling the valleys.

In the Spokane and Selkirk foothills ground, Ice Age flood gravel sits over the valley. That open gravel drains fast, which makes wet spots show up where fill has been compacted or a shallow basalt shelf holds water.

Water arrives as snowmelt in the high country. Most of the year's moisture leaves over a few weeks in spring, and it saturates valley soils while the ground below is still frozen.

Gravel valley floors drain; till and lake silt do not.

Frost governs unbound surfaces. Okanogan County publishes a 24 inch frost depth, and the Spokane Municipal Code design criteria uses 24 inches.

The county or city building department sets the figure, and it can run deeper at elevation.

Spring runoff scours ditches, culverts and gravel roads during breakup. Valley rivers cut their banks, and bare burned slopes shed soil and rock after a wildfire season.

The working season is short in the high country. Base, drive and paver work fits between spring breakup and the autumn freeze.

Eastern Washington's wet weather season for erosion control runs October 1 through June 30.

Choosing the Right Material

Pend Oreille County shares this county's Okanogan Highlands ground. The soil is the same glaciated mountain material: thin stony ground on the ridges, till and outwash gravel in the valleys.

Base and drainage choices follow the same reasoning.

Lincoln County sits on windblown loess over Columbia River basalt, in the Columbia Basin. Where the Ice Age floods ran, the loess was stripped and the basalt left bare, and the floods dumped sand and gravel bars in the coulees and along the rivers.

Elsewhere the silt sits deep.

That loess ground is fine-grained and holds water differently than the gravel and till here. On silt, a compacted granular base carries the load and keeps the surface out of the fines below.

Spokane County spans more than one zone, including the Spokane and Selkirk foothills ground that reaches into this county. Where the ground matches, the material reasoning matches too.
